For continuous operation without needing to empty the water tank, connect the included drain hose:

1. Locate the continuous drain outlet on the back or side of the unit.
2. Securely attach one end of the drain hose to this outlet.
3. Direct the other end of the hose to a suitable drain point (e.g., floor drain, sink), ensuring it is lower than the unit's drain outlet for gravity flow.
4. Ensure the hose is not kinked or blocked.

7. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your dehumidifier.

7.1. Emptying the Water Tank

When the water tank is full, the unit will automatically stop operating, and an indicator light will illuminate. Carefully remove the water tank from the unit, empty the collected water, and then reinsert the tank securely. Ensure the tank is properly seated to resume operation.

7.2. Cleaning the Air Filter

The air filter should be cleaned every two weeks or more frequently depending on usage and air quality. A dirty filter can reduce efficiency.

1. Unplug the dehumidifier from the power outlet.
2. Locate and remove the air filter (usually at the back or side).
3. Clean the filter with a vacuum cleaner or wash it gently with warm, soapy water.
4. Rinse thoroughly and allow the filter to air dry completely before reinstalling.
5. Reinsert the dry filter and plug the unit back in.

7.3. General Cleaning

Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the surface.

8. Troubleshooting

If you encounter issues with your dehumidifier, refer to the following common problems and solutions:

• Unit does not turn on:
  • Check if the power cord is securely plugged into a working outlet.
  • Ensure the water tank is properly inserted and not full.
  • Check if the child lock is activated.
• No water collected or low dehumidification:
  • Verify that the set humidity level is lower than the current room humidity.
  • Check if the air filter is clean and not blocked.
  • Ensure room temperature is above 5°C (41°F), as dehumidifiers are less effective in cold conditions.
  • Close doors and windows in the room to prevent humid air from entering.
  • Allow a few minutes for the unit to accurately measure humidity upon startup, as initial readings may be inaccurate.
• Unit is noisy:
  • Ensure the unit is on a stable, level surface.
  • Check for any obstructions in the air inlet or outlet.
  • Clean the air filter if it is dirty.
• Defrost function activates frequently:
  • This is normal in cooler environments (e.g., below 20°C). The unit temporarily stops dehumidifying to melt any ice buildup on the coils.

If the problem persists after trying these solutions, please contact Auronic customer support.
